COOKIES, UNDERSTAND IT ONCE AND FOR ALL!
There are many definitions out there for cookies, but the one I like the most is found on the Positivo website, as well as some other websites, which clarifies that cookies are simple text files sent by the website to the browser the first time you visit it. A simple and effective definition. It’s there so that when the user visits the website again, their browser sends the data collected by the cookie, depending on its goal.
